| pubmed-article:18252783 | pubmed:abstractText | Because IGF-I is the main mediator of GH action on osteogenic cells, individual differences in IGF-I sensitivity are expected to contribute to the variations of GH effects on growth. In GH-treated children, the variable responses in growth rates at a specific IGF-I target level indicate heterogeneity of responses to serum IGF-I exposures. | lld:pubmed |
